Trait Implementations

impl DomObject for Selection

fn reflector(&self) -> &Reflector

Returns the receiver’s reflector.

fn global(&self) -> Root<Dom<GlobalScope>>where
    Self: Sized,

Returns the global scope of the realm that the DomObject was created in.

impl DomObjectWrap for Selection

const WRAP: unsafe fn(_: SafeJSContext, _: &GlobalScope, _: Option<HandleObject<'_>>, _: Box<Self>) -> Root<Dom<Self>> = {dom::bindings::codegen::Bindings::SelectionBinding::SelectionBinding::Wrap as for<'a, 'b> unsafe fn(script_runtime::JSContext, &'a dom::globalscope::GlobalScope, std::option::Option<js::rust::Handle<'b, *mut js::jsapi::JSObject>>, std::boxed::Box<dom::selection::Selection>) -> dom::bindings::root::Root<dom::bindings::root::Dom<dom::selection::Selection>>}

Function pointer to the general wrap function type

impl HasParent for Selection

fn as_parent(&self) -> &Reflector

This is used in a type assertion to ensure that the source and webidls agree as to what the parent type is

type Parent = Reflector

impl IDLInterface for Selection

fn derives(class: &'static DOMClass) -> bool

Returns whether the given DOM class derives that interface.

impl JSTraceable for Selection

unsafe fn trace(&self, tracer: *mut JSTracer)

Trace self.

impl MallocSizeOf for Selection

fn size_of(&self, ops: &mut MallocSizeOfOps) -> usize

Measure the heap usage of all descendant heap-allocated structures, but not the space taken up by the value itself.

impl MutDomObject for Selection

unsafe fn init_reflector(&self, obj: *mut JSObject)

Initializes the Reflector

impl PartialEq<Selection> for Selection

fn eq(&self, other: &Selection) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl SelectionMethods for Selection

fn GetAnchorNode(&self) -> Option<Root<Dom<Node>>>

fn AnchorOffset(&self) -> u32

fn GetFocusNode(&self) -> Option<Root<Dom<Node>>>

fn FocusOffset(&self) -> u32

fn IsCollapsed(&self) -> bool

fn RangeCount(&self) -> u32

fn Type(&self) -> DOMString

fn GetRangeAt(&self, index: u32) -> Result<Root<Dom<Range>>, Error>

fn AddRange(&self, range: &Range)

fn RemoveRange(&self, range: &Range) -> Result<(), Error>

fn RemoveAllRanges(&self)

fn Empty(&self)

fn Collapse(&self, node: Option<&Node>, offset: u32) -> Result<(), Error>

fn SetPosition(&self, node: Option<&Node>, offset: u32) -> Result<(), Error>

fn CollapseToStart(&self) -> Result<(), Error>

fn CollapseToEnd(&self) -> Result<(), Error>

fn Extend(&self, node: &Node, offset: u32) -> Result<(), Error>

fn SetBaseAndExtent(

) -> Result<(), Error>

fn SelectAllChildren(&self, node: &Node) -> Result<(), Error>

fn DeleteFromDocument(&self) -> Result<(), Error>

fn ContainsNode(&self, node: &Node, allow_partial_containment: bool) -> bool

fn Stringifier(&self) -> DOMString

impl ToJSValConvertible for Selection

unsafe fn to_jsval(&self, cx: *mut JSContext, rval: MutableHandleValue<'_>)

Convert self to a JSVal. JSAPI failure causes a panic.
